GATE AND DOOR. CONTROL.

Application filed May 2, 1924.

To all whom it may concern:

Be it known that I, VVILBUR A. GooDwIN, a citizen of the United States,residing at Rainier, in the county of Thurston and State of lVashington,have invented a new 7 and useful Gate and Door Control, of which thefollowing is a specification.

This invention aims to provide novel and simple means whereby a door,gate or other barrier may be opened and closed by a moving vehicle, itbeing unnecessary for the driver of the vehicle to alight.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that sort to which the inventionappertains.

Although a preferred form has been shown, it will be understood that amechanic working within the scope of what is claimed, may make such.changes as his skill may dictate, without departing from the spirit ofthe invention.

In the drawings :-Figure 1 shows in elevation, a device constructed inaccordance with. the invention, parts appearing in section; Figure 2 isa top plan wherein parts are. sectioned away; Figure 3 is an elevationin which the device is viewed at right angles to the showing of Figure1; Figure 4 is a sectional detail showing the relation existing betweencertain of the levers and latches; Figure 5 is a sectional view showingthe cooperation between one of the levers and attendant parts; Figure 6is a fragmental sectional view wherein one of the latches,- is shown inholding relation to the barrier; Figure 7 is a top plan showing a slightmodification in the means for connecting the operating shaft with thebarrier.

The device forming the subject of this application may be used foroperating one or more doors for a garage, or one or more gates in theopen, but by way of illustration, the drawings show a support 1comprising a'hollow platform 20 and an upstanding frame 2, barriers 8being mounted at 4 on the frame 2, to swing horizontally. Top bars 5 aresecured to the barriers 3 and carry beveled gear wheels 6 locatedconcentrically with thepivotal mountings of the barriers 3.

The gear wheels 6v mesh with beveled pinions 7 secured to'a horizontalshaft 8, located above the barriers 3, and journaled in the frame 2.

Flexible members 9 and 10 are provided, the flexible. member 10including a cable or Serial No. 710,592.

the like, indicated at 11, and a retractile spring 12 connected to thecable, the flexible member 9 comprising a cable 14 and aretractilespring 15. The flexible elements 11 and 14 are wound in oppositedirections about the ends of the shaft 8, the lower end of the spring 15being connected to theoutcr endof a supplemental lever 16. A latch, 17is disposed parallel to the lever 16, the lever and the latch beingfulcrumed intermediate their ends; on thelower portion of the frame 2.At its outerend, the latch 17 has abeveled keeper 19, adapted to holdone of the barriers 3 in, an open posit-ion, and, in fact, to hold bothbarriers open, since the barriers are connected by the gear wheels 6 andthe pinions 7 with the shaft 8. l I V i V A main lever 22 is disposed atright angles to the lever 16 and the latch 17 and is fulcruined at 23,intermediate its ends, on the platform 20. A retractile spring 21 isconnected at its ends with the frame 2 and with the latch 17, and tends;to swing the inner end of the latch 17 downwardly on the inner end ofthe main lever 22 and to elevate the outer end of the latch 17 and thekeeper 19 into the position shown in Figure 1, so that, when thebarriers 3 ar opened, as hereinafter explained, one barrier will engageautomatically with the keeper, An auxiliary lever 24 is disposed inalinement with the main lever 22 and is located on the opposite sides ofthe barriers 3 from the main lever 22, the lever 24 being fulcrumed at25, intemncdiateits ends, on the platform 20. The inner end of theauxiliary lever 24 extends beneath. the inner end of the main lever 22,as shown in Figures4 and 3. At its outer end, the lever 22 carries atread plate 26 adapted to be engaged by a vehicle wheel, and the lever24 is provided at its outer end with a similar tread plate 27.

A main lever 28 is disposed parallel to the main lever 22 and is locatedon the same side of the barriers 3 as the lever 22, the lever 28 beiiigfulcrumed intermediate its end at 29 on the platform 20. At its. outerend, the lever 28 is supplied with a tread plate 30. A latch 81 islocated within the hollow plat form 20 and is fulcrumed intermediate itsends, as at 32, on the platform. Atits inner end, the latch 31 has abeveled keeper 33 operating in anopening 34 in the; platform 20. and;adapted. to engage both barriers 3,

'i to hold them closed. A rectractile spring 35 is connected to theinterior portion of the platform 20 and to the latch 31 and tends todraw down the outer end of the latch 31 and on the inner end of the mainlever 28. The spring 12 of the flexible member 10 is connected to theouter end of a supplemental lever 36, the inner end of the lever 36resting on the main lever 28, as shown in Figure 5, the lever 36 beingful crumed intermediate its ends, as at 37, on the lower portion of theframe 2. An auxiliary lever 38 is disposed on the opposite side of thebarriers 3 from the lever 28, the inner end of the lever 38 beingengaged beneath the inner end of the lever 28., the lever 38 beingfulcrumed intermediate its ends, as at 39, on the platform 20, and beingprovided at its outer end with atread plate 40.

Suppose that the barriers 3 are closed as in Figure 1 and that a vehicleapproaches in the direction of the arrow A in Figure 2. The vehicle isrun over the tread plate 30 and the lever 28 is tilted, the latch 31being tilted and the keeper 33 being disengaged from the barriers 3. Atthe same time, the lever 36 is tilted, the spring 12 is extended, andthe cable 11 is unwound from the shaft 8, the shaft 8 being rotated, andthe pinions 7 and the gear wheels 6 opening the barriers 3 until onebarrier engages behind the keeper 19 on the latch 17 to hold thebarriers open. After the vehicle has passed the open barriers 3, thevehicle is run over the tread plate 27 the lever 24 being tilted, thelever 24 tilting the lever 22, and the lever 22 tilting the lever 16 andthe latch 17, the keeper 19 being disengaged from the open barrier, andboth barriers being swung to closed position, when the lever 16 istilted, because the spring 15 is expanded and the cable 14 unwound fromthe shaft 8, reverse rotation being imparted to the shaft, and thepinions 7 cooperating with the gear wheels 6 to close the barriers 3,the barriers engaging again with the keeper 33 on the latch 31.

When the vehicle is moving in the direc tion of the arrow B in Figure 2,the vehicle is run over the tread plate 40, the lever 38 being operated,and the lever 38 operating the lever 28 to disengage the keeper 33 fromthe barriers and to open the barriers through the instrumentality of thelever 36 and the flexible member 10, as hereinbefore explained. Thevehicle finally is run over the tread plate 26, the keeper 19 isdisengaged from the open barrier, and the lever 16, together with theflexible member 9, operate to close the barriers.

When the device is used to operate a garage door, rather than a gate,the levers 38 and 24 may be omitted. Undersuch circumst-ances, thebarriers 3 are opened by means'of the lever 28 when the vehicle entersthe garage, and are closed by an operator. Likewise, when the vehicleleaves the garage, the barriers are opened by an operator and'are closedwhen the vehicle is run over the tread plate 26 on the lever 22.

Although two barriers 3 are shown, it will be obvious, without specificillustration, that the device will operate one barrier quite as well asit will operate two.

Passing to the modification shown in Figure 7, it will be obvious thatthe beveled gears 6 and 7 of Figure 1 need not be used to connect theshaft 8 with the barriers 3.v Thus in Figure 7 the barrier 11 may beprovided with a worm wheel 12 engaged with a worm 43 on a shaft 414,corresponding to the shaft 8, the flexible operating member for theshaft .4 1 being marked by the numeral 4C5.

I claim 1. In a device of the class described, a support, a barriermounted to swing on the support, a shaft journaled 011 the support,means for connecting the shaft operatively with the barrier, main leversfulcrumed intermediate their ends and located on the same side of thebarrier, the outer ends of the main levers being so located as to beengaged by a vehicle, supplemental levers fulcrumed intermediate theirends and 'disposed transverselyof the main levers, the inner ends of thesupplemental levers being engaged with the inner ends of the mainlevers, flexible members wound in opposite directions about the shaftand connected to the outer ends of the supplemental levers, latchesfulcrumed intermediate their ends and disposed approximately parallel tothe supplemental levers, the inner end of one latch cooperating with thebarrier to hold the barrier closed, and the outer end of said latchbeing engaged with the inner end of one main lever, and the outer end ofthe other latch cooperating with the barrier to kill] hold the sameopen, the inner end of the last specified latch being engaged with theinner end of the other main lever. 2. A device of the class described,constructed as set forth in claim 1, and further characterized by theprovision of auxiliary levers disposed on the opposite side of thebarrier from the main levers and having their outer ends so located asto be engaged by a vehicle, the inner ends of the auxiliary levers beingengaged with the inner ends of the main levers, and the auxiliary leversbeing fulcrumed intermediate their ends.
